Sure.

> Regarding the duplicate vport delete request, I have not found a way to generate such request from userspace. When I use 'ovs-vsctl' application to send a second delete request for a VXLAN interface, the app outputs an error message to the console without sending the delete request to the kernel.

No, OVS userspace takes care of this already. It would make sure that a duplicate request does not get issued concurrently on multiple threads. I was only speaking from a general “kernel robustness” perspective. IMO, a kernel module should always be resilient to any userspace bugs.
